  1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fawzi Kayali; [2023]
    Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

  3. 2. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Simon Dahl; [2023]
    Keywords : Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

  4. 3. Heat recovery from vacuum brazing furnaces

    University essay from Lunds universitet/Avdelningen för Installations- och klimatiseringslära

    Author : Oliver Robertsson; Rasmus Wikman; [2023]
    Keywords : Waste heat; Vacuum furnace; Heat recovery; HVAC; Technology and Engineering;

    Abstract : By partly replacing the use of primary energy sources with waste heat recovery, climate and environmental goals for the future will be closer at hand. This thesis investigates the waste heat potential of Alfa Laval's vacuum brazing furnaces in Ronneby and alternative ways of integrating the furnace's waste heat into the building's HVAC system.

  5. 4. MINERAL CARRYOVER FROM SHELLED MUSSEL MEAL IN THE SPOTTED WOLFFISH (ANARHICHAS MINOR). Potential of dietary mineral supplementation on growth, stress and health.

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Terese Hjelleset; [2022-08-16]
    Keywords : ;

    Abstract : The potential of Swedish aquaculture is currently not fulfilled as Sweden is still a net importer of fish with low production and narrow species diversity. In recent years, there has been increasing interest in expanding and diversifying Swedish aquaculture to make it more sustainable and competitive. READ MORE

  6. 5. Some Like It Hot: Pre-heating Prior to Bioreactor Treatment Enhances Nitrogen Removal From Mine Drainage

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Laura Nina Bettoni; [2022]
    Keywords : denitrification; nitrate removal; temperature; woodchip bioreactor; waste rock leachate;

    Abstract : Ammonium-nitrate based explosives (NH4NO3) used within the operations of Kiruna iron ore mine release nitrate (NO3-) into the environment, potentially having adverse effects on local river-systems. One way of reducing NO3- impacts to the environment is through a woodchip denitrifying bioreactor (DBR). READ MORE
